Weeds in st. Augustine grass!
My neighbor sprays his clippings in my yard when he mows. My yard was weed free and now that part is mostly weeds. What can I do to get rid of the weeds?
First of all, keep your own grass as healthy as possible with good water management and fertilization.
It depends on what kind of weeds are growing in your grass lawn. If they are "broadleaf" weeds, you can apply a selective herbicide that kills only the broadleaf plants and not the grasses.
